Hi! Can you help me with my code? I attached a copy below #include <DS3231.h> #include <Servo.h> #include <LiquidCrystal.h> #include <Keypad.h> const byte ROWS = 4; //four rows const byte COLS = 4; //four columns char keys[ROWS][COLS] = { {'1','2','3',}, {'4','5','6',}, {'7','8','9',}, {'*…

Your program does not have a function named setup() in it, nor does it have a function named loop() Look at any of the example programs to see how these two mandatory functions are used

Hi, Can you post your complete code please. Thanks for using code tags.. :slight_smile: Tom.. :slight_smile:

Hi Tom, here are the codes. #include <DS3231.h> #include <Servo.h> #include <LiquidCrystal.h> #include <Keypad.h> const byte ROWS = 4; //four rows const byte COLS = 4; //four columns char keys[ROWS][COLS] = { {'1','2','3',}, {'4','5','6',}, {'7','8','9',}, {'*','0','#',} }; byte rowPins[RO…

DS3231 rtc(A4, A5); What are the two pin numbers for ? Have you looked at the examples with the library ? Do you need to #include the Wire library ?

I am beginner so I don't know much :confused: I attached two diagrams below. I'm a college student, assigned for arduino project but I have no basic in programming. [Automatic-Pet-Feeder-circuit-diagram-using-Arduino.png] [IMG_20181002_172854_797.jpg]

Let me suggest a site to you. Have you heard of Hackster.io ? You could look for answers for Arduino projects and problems there. Hope this helped.

nazdmiii: I am beginner so I don't know much :confused: I attached two diagrams below. I'm a college student, assigned for arduino project but I have no basic in programming. So, you have the DS3231 connected to pins A4 and A5 but these pins have a special function when used with the Wire libra…
